Questions[asterisk](ubuntu)

I use a certain piece of sofware (Asterisk) which includes in its source tree a nifty little script to automatically download and install all packages it needs from your distro's repositories, including of course Ubuntu. One of these prerequisites (libvpb1) requires a piece of information (the default country phone prefix), so the script becomes not so automatic:

It's innocuous to have this library installed in a system that doesn't run telephony stuff, so you can test it yourself.

My question is: How do I feed the answer non-interactively beforehand so apt-get install (or, rather, dpkg -i) grabs that and uses it as if it had been typed in that ncurses screen?

A generic solution would be better, like, how do I know if any package requires information like this, and how do I set it from a script?

Given that Jitsi won't install nicely from apt how is the desktop client currently installed?

There's mention above of using the unstable repo.

These directions won't work for at least one other:

Jitsi
Download
Development
Documentation
    Support and Custom Development 

To use our debian/ubuntu stable repository:

install the Jitsi repository key onto your system

wget -qO - https://download.jitsi.org/jitsi-key.gpg.key | sudo apt-key add -

create sources.list.d file with the repository

sudo sh -c "echo 'deb https://download.jitsi.org stable/' > /etc/apt/sources.list.d/jitsi-stable.list"

update your package list

sudo apt-get -y update

install Jitsi

sudo apt-get -y install jitsi

Adding both repos:

nicholas $ 
nicholas $  wget -qO - https://download.jitsi.org/jitsi-key.gpg.key | sudo apt-key add -
OK
nicholas $ 
nicholas $  sudo sh -c "echo 'deb https://download.jitsi.org stable/' > /etc/apt/sources.list.d/jitsi-stable.list"
nicholas $ 
nicholas $  sudo sh -c "echo 'deb https://download.jitsi.org unstable/' > /etc/apt/sources.list.d/jitsi-unstable.list"
nicholas $ 

commenting out the stable repo and updating:

nicholas $ 
nicholas $ cat /etc/apt/sources.list.d/jitsi-stable.list 
#deb https://download.jitsi.org stable/

Some packages could not be installed. This may mean that you have
requested an impossible situation or if you are using the unstable
distribution that some required packages have not yet been created
or been moved out of Incoming.
The following information may help resolve the situation:

The following packages have unmet dependencies:
 jitsi : Depends: libavformat57 but it is not installable or
                  libavformat-ffmpeg56 but it is not installable
         Depends: libavcodec57 but it is not installable or
                  libavcodec-extra57 but it is not installable or

which then has unmet dependencies. Oh, the unstable repo:

I'm trying to make modifications to the srtp module used by Asterisk. Linker from Asterisk to srtp is via res_srtp.so which will use the srtp libsrtp.1.so shared object.

res_srtp.so --> libsrtp2.so.1

When I rebuilt the srtp library, sometimes I managed to do it but sometimes it failed. The meaning of failing here is that the existing srtp configuration still uses the previous configuration file which I haven't changed. I wonder why this happened, even though I used the same command sequence in building the library. The following is the sequence of commands that I use.

make uninstall
make clean
./configure
make
make shared_library
make install

note : I change from code A to code B and then change again to code A

I'm trying to install asterisk-15.4.0 with

roman@romanPC:~/asterisk-install/asterisk-15.4.0$ sudo ./contrib/scripts/install_prereq install

At some point it says:

The following actions will resolve these dependencies:

  Remove the following packages:                                 
1)      apturl                                                       
2)      hwdata                                                       
3)      libcurl4-gnutls-dev                                          
4)      nautilus-share                                               
5)      nvidia-prime                                                 
6)      pciutils                                                     
7)      software-properties-gtk                                      
8)      ubuntu-desktop                                               
9)      ubuntu-drivers-common                                        
10)     ubuntu-standard            

and

The following packages will be REMOVED:
  apturl{a} bbswitch-dkms{u} hwdata{a} libcurl4-gnutls-dev{a} nautilus-share{a} nvidia-prime{a} 
  pciutils{a} software-properties-gtk{a} ubuntu-desktop{a} ubuntu-drivers-common{a} 
  ubuntu-standard{a} 

and further

Removing hwdata (0.267-1) ...
Removing libcurl4-gnutls-dev:amd64 (7.47.0-1ubuntu2.7) ...
Removing ubuntu-standard (1.361.1) ...
Removing ubuntu-desktop (1.361.1) ...
Removing software-properties-gtk (0.96.20.7) ...
Removing ubuntu-drivers-common (1:0.4.17.7) ...
Removing pciutils (1:3.3.1-1.1ubuntu1.1) ...

Is that OK? Why does it have to delete such packets as ubuntu-desktop? Should I be worried? Should I fix this or leave it alone?

My OS: Ubuntu 16.04.4 LTS

It also said (I don't know, maybe that helps):

The following packages were automatically installed and are no longer required:
  linux-headers-4.13.0-36 linux-headers-4.13.0-36-generic linux-headers-4.13.0-37
  linux-headers-4.13.0-37-generic linux-headers-4.4.0-119 linux-headers-4.4.0-119-generic
  linux-image-4.13.0-36-generic linux-image-4.13.0-37-generic linux-image-4.4.0-119-generic
  linux-image-extra-4.13.0-36-generic linux-image-extra-4.13.0-37-generic
  linux-image-extra-4.4.0-119-generic

Here is the whole log. Thanks.

I have been trying to get a2billing to work for the past 4 days now, i followed 4 tutorials and they all gave me some insight into how things work.. but the a2billing is still not working..

my Asterisk works fine, freepbx i can make extension and place calls on trunks OK, internals perfect...

I installed a2billing.. the admin,user,agents.. all that works - i can log in add rates,trunks, the simulator get the correct routes,rates and trunks..

I can make a user log in using a sip device.. but for the love of god.. every single time i dial I get error q931_disconnect_code_21

ISDN Code says-- Cause No. 21 - call rejected. This cause indicates that the equipment sending this cause does not wish to accept this call. although it could have accepted the call because the equipment sending this cause is neither busy nor incompatible. This cause may also be generated by the network, indicating that the call was cleared due to a supplementary service constraint. The diagnostic field may contain additional information about the supplementary service and reason for rejection.

Which means the host(a2billing and asterisk) knows about the call but activbely denied routing the call.. IN the simulator i use the same number that works in there on my sip.

I am on Ubuntu 10.4LTS - Asterisk was installed using apt-get -> /usr/share/asterisk but i also have a /var/lib/asterisk

i made a ln -s to /usr/src/a2billing/AGI/a2billing.php /usr/share/asterisk/agi-bin (the asterisk conf defines this as the agi location-and freepbx time,freebpx echo works)

Another problem is that a2billing has not made 1 single log file and i cannot determine what the heck is going on(the permissions are set write global and belong to asterisk).. asterisk logs are clean.. sip, trunks are all registered.

I connect to a2billing user, place call-- silence. and just error q931(zoiper on iphone) if i use the freepbx extension i can talk with anybody iusing freepbx routes.

I followed this guide http://www.data4ict.com/tutorials/a2billing/a2billing.asp

basically i skipped freepbx out of the picture, so its just asterisk direct to a2billing.. and all the steps and verifications are just like he shows (execpt i use /usr/share/asterisk instead of /var/lib/asterisk... ??.. step by step idiot tutorial and i still cant get it working.

I set all the version to 1_6, permissions are good- i even wrote test into the a2billing_agi.log and it shows the test string on the admin end.. but never writes anything to the log file.

apache2 runs runs as www-data:www-data asterisk runs as asterisk:asterisk freepbx (i disabled it for now but runs as asterisk)

I made links to both var and usr agi-bin folder back to placed the a2billing.php with the lib link

my current config is like the ones in the turorial extensions,sips,iax'as

A2Billing 1.9.4 (Cuprum)

Has anybody have any suggestion how to debug what is going on. Maybe if i can jsut get the logs to work that will help.. I am really bumbed out now .. 5days later.

Or is there a ready to go a2billing distro i dont know about maybe....

EDIT

So I rented a freelancer(experienced)... he sat like 4 hours, doing wierd comamnds and things...

Still not fixed.. Im just going to format and redo the while thing - It seems like i must have missed something
